Unit designed to provide uninterrupted DC power in the event of loss of the primary 110 / 220 VAC supply. It utilizes a 12 V sealed lead acid battery as a source of power until the AC supply can be restored. It is a versatile unit which can be used in a number of different applications. The outputs are +5 VDC @ 6.5 A, + 3.3 VDC @ 2.5 A, +12 VDC @ .8 A, -12 VDC @ .5 A, and a battery charging output of 12 VDC @ 10 A. The DC outputs are terminated in in-line connectors which interface with standard motherboard and drive connectors. Possible applications include: Robotics, scientific sensing and recording, Linux devices attached to Ethernet or Internet links, etc...

The unit is small enough (2” x 3.5” x 8.5”) to be contained in a standard PC enclosure, in place of the regular power supply - interfacing directly with the motherboard - providing an uninterruptable power supply

It can function as a DC - DC power supply furnishing multiple outputs using a 12 VDC input.

The 10 Amp, 12 VDC out put can be used as a battery charger with any AC input from 100 -240 V

The unit is a versatile 57 watt DC power supply providing +5 and 3.3 VDC as well as +/- 12 VDC.

Cell Site Transceiver $19.00 or 2 for $29.00

These transceivers were designed for operation in an AMPS (Advanced Mobile Phone Service) cell site. The 20 MHz bandwidth of the transceiver allows it to operate on all 666 channels allocated. The transmit channels are 870.030-889.980 MHz with the receive channels 45 MHz below those frequencies. A digital synthesizer is utilized to generate the selected frequency. Each unit contains two independent receivers to demodulate voice and data with a Receive Signal Strength Indicator (RSSI) circuit to select the one with the best signal strength. The transmitter provides a 1.5 watt modulated signal to drive an external power amplifier. Channel selection is accomplished with a 10 bit binary input via a connector on the back panel. Other interface requirements for operation are 26 VDC (unregulated) and an 18.990 MHz reference frequency for the digital synthesizer. The units contain independent boards for receivers, exciter, synthesizer, tunable front end, and interface assembly (which includes power supplies and voltage - controlled oscillator). Service manual, schematics and circuit descriptions included.

Embedded 486 Computer $69.00 or 2 for $149.00

Complete enhanced Intel 486SX-33 based computer in ultra small (9-7/8L x 6-5/8W x 3-1/8H)case, Ideal for embedded operations or as a second computer.

Note: We have not been able to bypass an access code in the software. Thus, while time of day and other introductory things are displayed on LCD, the full original capabilities of this unit can not be guaranteed. Also, we do not have a source for the smart cards that were to go in the PCMCIA sockets. Requires 12 volt adapter for power (not included). Original price $450.00

Board will not fit standard All in One case because of non standard location of riser board.

Encased Spread Spectrum RF Modem $99.00

The ProxLink Radio Module is a small communication device which replaces cables between RS-232 devices with wireless RF (Radio Frequency) technology. Attaching a pair of ProxLinks to any two devices with three wire asynchronous RS-232 ports allows wireless data transmittal at rates up to 19.2 Kbaud (full duplex) over a range of 500 - 800 feet. Modules use 900 MZ spread spectrum radio for communication which does not require an FCC site license. A variety of configuration information (radio channel, baud rate, serial port configuration, etc.) can be programmed into module's non-volatile memory by host PC to provide compatibility and avoid overlapping systems.Configuration changes are supported by menu driven, on-board software. Commonly used Terminal Emulation software and transfer protocols can be used for configuring modules and transferring data between computers. ProxLinks require only 6-9 VDC (350 mA), RS-232 (9 pip sub - D) interface, and small (~4") whip antenna for operation. Unit size is 4.0" x 6.5" x 0.75". Installation schematics and application details available.
